ONNECTIONS
To connect the shelves using the 10BASE-T Ethernet connectors ( Figure 2-4 ):
Figure 2-4. 10BASE-T Multishelf Cable Connections
Note: Multishelf networks cannot be connected through a router because the local shelf uses UDP-
broadcast messages as a mechanism to automatically discover other shelves in the network, and routers
generally filter these broadcasts. A multishelf network is limited to 32 shelves.
Step Action
1 Plug an RJ-45 cable into the 10BASE-T connector at the rear of each shelf.
2 Plug the other end of the RJ-45 cables into the hub/switch connecting the shelves.
Note: The length of each RJ-45 cable cannot exceed 100 meters (328 feet).
